Ports and Protocols Explained
The key to setting up a Remote Console is knowing which ports to use. The important factor is knowing
what ports are in use on the network and using ports that will not conflict with those. By default, Deep
Freeze uses port 7725.
The following three components make up the Deep Freeze Architecture:
• Client (with workstation or seed installed)
• Remote Console (Server Service or RCE Console)
• Console (connects to the Remote Console)
Using the following rules, there should not be any port conflicts between the different components:
• The clients and Remote Console should use the same port.
• The consoles that connect to the Remote Console need to be created under a different port
than the Remote Console. This prevents the consoles from conflicting with the Remote
Console when they are both run inside the same subnet.
• One console that connects to the Remote Console can use the same local port as another
console connecting to the Remote Console. These consoles do not conflict with one another,
even though they are on the same subnet, because there are no clients involved on the local
port.
The following diagram gives a theoretical view of the Port Settings:

Ports can also be used to divide the clients when using the Server Service. If the Server Service is set
up to run under three ports (7725, 7724 and 7723), consoles can connect to the three different ports
to see a different set of clients under each port. An example showing this type of architecture is shown
subsequently in
Example 4 - Multiple Subnets Central Server Services.
In the diagram above, the client(s) use both the TCP and UDP protocols to communicate with the
Remote Console. The console(s) that connects to the Remote Console uses only the TCP protocol to
communicate with the Remote Console. It is important to remember the ports and protocols being
used in order to prevent fire walls, switches, or routers from blocking them.
